(1) Background: Most factors that predict the in-hospital survival rate in patients with severe trauma are patient-related factors; environmental factors are not currently considered important. Predicting the severity of trauma using environmental factors could be a reliable and easy-to-use method. Therefore, the purpose of this study was to determine whether environmental factors affect the survival in patients with severe trauma. (2) Methods: Medical records of patients who activated trauma team in the single regional trauma center, from 2016 to 2020, were retrospectively analyzed. After exclusion of young patients (<19 years old), cases of mild trauma (ISS < 16), and non-preventable deaths (trauma and injury severity score <25%), a total of 1706 patients were included in the study. (3) Results: In the Cox proportional hazard regression analysis, older age, night compared with day, and high rainfall were identified as statistically significant environmental predictors of mortality due to severe trauma. The relationship between mortality and precipitation showed a linear relationship, while that between mortality and temperature showed an inverted U-shaped relationship. (4) Conclusions: Various environmental factors of trauma affect mortality in patients with severe trauma. In predicting the survival of patients with severe trauma, environmental factors are considered relatively less important, though they can be used effectively.
(1) 背景：大多数预测严重创伤患者院内生存率的因素是与患者相关的因素；目前环境因素不被认为是重要因素。利用环境因素预测创伤严重程度可能是一种可靠且易于使用的方法。因此，本研究的目的是确定环境因素是否会影响严重创伤患者的生存率。(2) 方法：回顾性分析了2016年至2020年在单一区域创伤中心启动创伤团队的患者的病历。排除年轻患者（<19岁）、轻度创伤病例（损伤严重度评分<16）和不可预防的死亡病例（创伤和损伤严重度评分<25%）后，共有1706例患者纳入本研究。(3) 结果：在Cox比例风险回归分析中，年龄较大、夜间与白天相比以及高降雨量被确定为严重创伤导致死亡的具有统计学意义的环境预测因素。死亡率与降水量之间呈线性关系，而死亡率与温度之间呈倒U形关系。(4) 结论：创伤的各种环境因素会影响严重创伤患者的死亡率。在预测严重创伤患者的生存率时，环境因素虽然可以有效利用，但相对而言被认为不太重要。
